章節(jié)摘錄

　　Aerial Surveying　 An engineer may have air-photographsof a site on which he has to design or set out works. It is impor-tant that he should understand their uses and limitations.Though an air-photograph will probably show all the detailsthe engineer requires， and indeed probably very much more， itmust not be treated as a map because it is not possible to ensurethat the axis of an air-camera is exactly vertical. The tilt may beseveral degrees in a so-called vertical photograph， so there maybe appreciable differences of scale between opposite sides of aphotograph. In any case， even if the camera axis is vertical， therelative positionS of points at different heights will not be cor-rectly shown.The most valuable property of an air-photograph is that an-gles round a point at or close to its center may be regarded ascorrect， and in making maps from air-photographs this propertyis exploited. In other words， a near-vertical air-photograph maybe regarded as a record of angles taken at its center point or anypoint very close to the center.
